You could. I'm just saying that there is a broader use case than just
@longdesc for images here and that it may be useful to introduce a
general solution for it. You might want to use the attribute name
@longdesc for it, or you might want to use a new one to avoid conflict
and confusion with existing uses. The new one would also come with a
recommendation for consistent visual presentation.
